Error responses
If your query fails, the API will return false in the success parameter, also HTTP header code 404 Not Found or HTTP 521 Timeout.
Which type of historical rates does the API offer?
The API delivers EOD / End of Day historical exchange rates, which become available at 00:05 am GMT for the previous day and are time stamped at one second before midnight.
Rate Limits
API requests made by a throttled user or app will fail. All API requests are subject to rate limits. Real time rate limit usage statistics are described in headers that are included with most API responses once enough calls have been made to an endpoint.
Response showing old date
API requests are cached by default. You can try to add an additional parameter &v=_actual_date_ in the query, where _actual_date_ enter the day in the format for example Y-m-d (or you can add only hour value).
What happens if my allowed volume is exceeded?
Users exceeding their monthly API request limit receive automated email and dashboard notifications at 75%, 90%, and 100%. After reaching 100% of the allowance, overages fees will apply so we make sure you won’t experience any disruptions and your website/application will keep running smoothly. You can learn more about overages billing here.
